BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a display control apparatus, a display control method, and a program.

2. Description of the Related Art

In recent years, a device having an imaging function for imaging a still image and/or moving image such as a digital still camera, a digital video camera including a “Handycam”, which trademark right is given to the applicant of the subject application, and a mobile telephone having a digital camera function is being widespread used. The frequency the user performs imaging increases and the number of imaged images also increases by providing the imaging function to the portable device such as the mobile telephone. The storage medium of the recording medium for storing the imaged images is also increasing, where great number of images can be recorded in one recording medium.

The device having such imaging function can record the imaged image in the removable recording medium such as a Memory Stick. The images recorded in the recording medium can be reproduced and the like in other devices different from the device that imaged the image by recording the images in the removable recording medium.

A technique for improving the efficiency in the process of searching and displaying a list of images recorded in the recording medium is being developed. The technique of storing a data base in which an image and information related to the image are corresponded in the recording medium to improve the efficiency in the process desired in the similarly search of images, displaying of list of images satisfying a predetermined condition and the like using a database is described Japanese Patent Application Laid-Open No. 2007-206918.

SUMMARY OF THE INVENTION

The device applied with the technique of the related art for improving the efficiency in the process of searching and displaying a list of images recorded in the recording medium, improves efficiency of the process by using the database. Thus, the device applied with the technique of the related art can provide functions such as similarly search of images and displaying of list of images satisfying a predetermined condition to the user using the relevant device, whereby the convenience of the user improves. However, the device applied with the technique of the related art may not improve the efficiency in process if the database does not exist in the recording medium, and thus the convenience of the user may not be enhanced.

The device applied with the technique of the related art may not be able to automatically display the recorded images if the database is not referenced even if the images are recorded in the recording medium. In such case, the user desirably has the device applied with the technique of the related art read out the images recorded in the recording medium through manual operation, which significantly lowers the operability of the user.

One method of enhancing the convenience of the user when the database does not exist in the recording medium includes having the device for reading out the images recorded in the recording medium perform the following processes (a) to (d).

(a) The device for reading out the images recorded in the recording medium newly creates a database if the database does not exist in the recording medium.

(b) The device for reading out the images recorded in the recording medium analyzes each image recorded in the recording medium, and derives information related to the image.

(c) The device for reading out the images recorded in the recording medium corresponds the image and the information related to the image based on the information related to the image derived in the process of (b), and registers the same in the database created in the process of (a).

(d) The device for reading out the images recorded in the recording medium selectively reads out the images recorded in the recording medium using the database registered in the process of (c).

The device for reading out the images recorded in the recording medium can improve the efficiency in process of searching and displaying a list of images using the created database by performing the processes (a) to (d). In the device for reading out the images recorded in the recording medium, the effect of enhancing the convenience of the user can be expected by performing the processes (a) to (d). Furthermore, in the device for reading out the images recorded in the recording medium, the possibility an event the database is not referenced occurs can be reduced by performing the processes (a) to (d), and thus the possibility an event the operability of the user significantly lowers occurs can also be reduced.

However, when the device for reading out the images recorded in the recording medium performs the processes (a) to (d), the device analyzes the images recorded in the recording medium and derives the information related to the image. For instance, if 10000 still images are recorded in the recording medium, the device for reading out the images recorded in the recording medium desires great amount of time for processing if it takes a few dozen minutes to simply perform the processes (a) to (c). If the processing time of a few dozen minutes is desired, the operability of the user significantly lowers even if the device for reading out the images recorded in the recording medium is able to enhance the convenience of the user by performing the processes (a) to (d).

Therefore, in the device applied with the technique of the related art to improve the efficiency in processes such as searching and displaying a list of images recorded in the recording medium, both the convenience and the operability of the user may not be enhanced when displaying the images recorded in the recording medium.

The present invention addresses the above-identified, and other issues associated with methods in related art and apparatuses, and it is desirable to provide a new and improved display control apparatus capable of enhancing both the convenience and the operability of the user when displaying the images recorded in the recording medium, a display control method, and a program.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Hereafter, preferred embodiments of the present invention will be described in detail with reference to the appended drawings. Note that in this specification and the appended drawings, structural elements that have substantially the same functions and structures are denoted with the same reference numerals and a repeated explanation of these structural elements is omitted.

The description is made in the following order.

1. Approach related to embodiment of the present invention

2. Display control apparatus according to embodiment of the present invention

3. Program related to display control apparatus according to embodiment of the present invention

The recording medium for recording the images will be described below using a recording medium (hereinafter sometimes referred to as “external memory”) removable from the display control apparatus and a recording medium (hereinafter referred to as “internal memory) arranged in the display control apparatus by way of example. The following description is mainly made assuming that the display control apparatus displays the images recorded in the external memory, but it is not limited thereto. The display control apparatus according to an embodiment of the present invention may display the images recorded in the internal memory similar to the images recorded in the external memory. Furthermore, the image related to the embodiment of the present invention may be a still image or a moving image.

(Approach Related to Embodiment of the Present Invention)

Prior to describing the configuration of the display control apparatus (hereinafter sometimes referred to as “display control apparatus 1000”) according to an embodiment of the present invention, the approach for enhancing the convenience and the operability in the display of images recorded in the recording medium according to the embodiment of the present invention will be described.

As described above, the device applied with the technique of the related art for improving the efficiency in processes such as searching and displaying a list of images recorded in the recording medium can enhance the convenience of the user by using the database but may affect the operability. As described above, the device applied with the technique of the related art may lower the operability of the user even if the processes (a) to (c) are performed.

The display control apparatus 1000 according to the embodiment of the present invention performs the following processes (A) to (C) to enhance the convenience and the operability in the display of images recorded in the recording medium (external memory/internal memory. This is the same hereinafter).

[Outline of Process in Display Control Apparatus 1000]

(A) Recognition of Database Recorded in Recording Medium

The display control apparatus 1000 recognizes the database recorded in the recording medium based a predetermined criterion. The predetermined criterion in the display control apparatus 1000 includes, for example, “whether database is recorded in the recording medium” and “whether number of images registered in the database exceeds a predetermined number”, but is not limited thereto.

(B) Setting of Display Method Based on Recognition Result of Database

The display control apparatus 1000 sets the display method (hereinafter sometimes referred to as “display mode”) of the image based on the recognition result in the process of (A). More specifically, the display control apparatus 1000 sets a stored first display method if the predetermined criterion is met based on the recognition result in the process of (A). The display control apparatus 1000 sets a second display method of displaying the images stored in the recording medium without using the database if the predetermined criterion is met based on the recognition result in the process of (A).

The display control apparatus 1000 sets the stored display method (first display method) such as display method set recently if determined that the predetermined criterion is met based on the recognition result in the process of (A). Since the database can be used if the predetermined criterion is met, the display control apparatus 1000 can display the images recorded in the recording medium using the database even if the stored display method uses the database. When the first display method is set, the display control apparatus 1000 does not require great amount of time in the process as in the device for performing the processes (a) to (d) even if the stored display method uses the database. Therefore, the display control apparatus 1000 can enhance the convenience and the operability of the user in the display of images by setting the first display method.

The display control apparatus 1000 sets the display method (second display method) that does not use the database if the predetermined criterion is not met based on the recognition result in the process of (A). Therefore, in the display control apparatus 1000, an event in which the images recorded in the recording medium is not automatically displayed as in the device applied with the technique of the related art does not occur. Furthermore, in the display control apparatus 1000, great amount of time is not required for the process as in the device for performing the processes (a) to (d). Therefore, the display control apparatus 1000 can enhance the convenience and the operability of the user in the display of images even if the second display method is set.

[Example of Display Method According to Embodiment of the Present Invention]

One example of the display method according to the embodiment of the present invention is shown. The display method according to the embodiment of the present invention can be broadly classified into [B-1] display method not using database and [B-2] display method using database.

[B-1] Example of Display Method Not Using Database (FIG. 1)

FIG. 1 is an explanatory view showing a first example of the display method according to the embodiment of the present invention, and shows one example of the display method not using the database. FIG. 2 is an explanatory view showing a second example of the display method according to the embodiment of the present invention, and shows the display method of when the user selects one image from a list of images shown in FIG. 1.

For the display method not using the database, the display control apparatus 1000 displays, by folders, a list of images stored in a folder (or also referred to as “directory”) managed according to the DCF (Design rule for Camera File system) standard and the like. FIG. 1 shows an example showing a list of images stored in a folder 101 (so-called thumbnail display). The display method of displaying the images by folders is hereinafter referred to as “folder view mode”.

When the user of the display control apparatus 1000 selects one of the images (thumbnail images) shown by the folder view mode, the display control apparatus 1000 displays the selected image on the entire display screen, as shown in FIG. 2. It should be recognized that the display control apparatus 1000 can arbitrarily transition from the display state of FIG. 2 to the folder view mode shown in FIG. 1 or to other display methods to be hereinafter described in response to the operation of the user.

[B-2] Display Method of Using Database

An example of the display method using the database according to the embodiment of the present invention will be described. The display method using the database according to the embodiment of the present invention includes “date view mode”, “favorite view mode”, and the like.

[B-2-1] Date View Mode (FIG. 3)

FIG. 3 is an explanatory view showing a third example of the display method according to the embodiment of the present invention, where a list of images imaged on Oct. 10, 2007 is shown. As shown in FIG. 3, the display method of showing a list of images by selectively extracting images imaged on a specific date from the images recorded in the recording medium is referred to as “date view mode” in the present embodiment. The display control apparatus 1000 references the database based on the date specified by the user to realize the date view mode as shown in FIG. 3. In the database, the images recorded in the recording medium and the information (one example of information related to image) of the date on which the relevant image is imaged are corresponded and recorded. The specific example of the database according to the embodiment of the present invention will be hereinafter described.

[B-2-2] Favorite View Mode (FIG. 4)

FIG. 4 is an explanatory view showing a fourth example of the display method according to the embodiment of the present invention, where a list of images imaged at the beach is shown. FIG. 4 shows one example of the display screen displayed as a result of the user editing the images imaged at the beach and collecting the images in a display group “favorite 1”. The display device 1000 references the database in which the images recorded in the recording medium and a flag (one example of information related to image) indicating favorite are corresponded and recorded to selectively display a specific image set with the flag. The flag indicating favorite is directly set by the user operation, but is not limited thereto, and may be indirectly set by the display control apparatus 1000 based on the condition specified by the user (e.g., “image of beach” etc.). The display method of showing a list of images set with the flag indicating favorite as shown in FIG. 4 is referred to as “favorite view mode” in the embodiment of the present invention.

The display control apparatus 1000 can display the image that matches the specific condition from the images recorded in the recording medium as in the date view mode shown in FIG. 3 and the favorite view mode shown in FIG. 4 by using the database. Therefore, the display control apparatus 1000 can enhance the convenience of the user. It should be recognized that the display method using the database according to the embodiment of the present invention is not limited to the date view mode and the favorite view mode. For instance, the display control apparatus 1000 can use the display method (so-called event view mode) of selectively displaying the image (e.g., image set with predetermined flag) imaged at a specific event for the display method using the database.

In the display control apparatus 1000, the display method as described [B-1] (folder view mode), [B-2-1] (date view mode), [B-2-2] (favorite view mode) is used. The first display method according to the embodiment of the present invention corresponds to the display method of one of [B-1] (folder view mode), [B-2-1] (date view mode), [B-2-2] (favorite view mode). The second display method according to the embodiment of the present invention is the display method of displaying without using the database, and corresponds to [B-1] (folder view mode).

(C) Display Control Based on Set Display Method

The display control apparatus 1000 controls the display of image on the display screen based on the display method (first display method/second display method) set in the process of (B).

The display control apparatus 1000 displays the images recorded in the recording medium on the display screen by the display method of either the stored first display method or the second display method not using the database by performing the processes of (A) to (C).

Here, the display control apparatus 1000 displays the image using the database when the stored display method is the display mode using the database when the first display method is set. The display control apparatus 1000 does not perform the process of registering the image in the database even if the stored display method uses the database, and thus great amount of time is not required in the process as in the device of performing the processes (a) to (d). The display control apparatus 1000 displays the images recorded in the folder by folders when the stored display method is the display mode not using the database when the first display method is set (folder view mode).

When the second display method is set, the display control apparatus 1000 does not display the image using the database. Therefore, when the second display method is set, an event where the images recorded in the recording medium is not automatically displayed as in the device applied with the technique of the related art does not occur in the display control apparatus 1000. When the second display method is set, the display control apparatus 1000 does not perform the process of registering the image in the database, and thus great amount of time is not required as in the device for performing the processes (a) to (d).

Therefore, the display control apparatus 1000 enhances the convenience and the operability of the user in the display of images by performing the processes (A) to (C).

[Details of Process in the Display Control Apparatus 1000]

The process in the display control apparatus 1000 will be specifically described below.

FIRST EXAMPLE

FIG. 5 is a flowchart showing a first example of the flow of process in the display control apparatus 1000 according to the embodiment of the present invention. FIG. 5 shows an example of the process of when the display control apparatus 1000 displays the images recorded in the external memory (recording medium).

The display control apparatus 1000 determines whether or not the external memory is detected (S100). The display control apparatus 1000 performs the determination of step S100 when the external memory is accommodated in an external memory accommodating unit based on the detection signal transmitted from the detection sensor for detecting the insertion of the external memory arranged in the external memory accommodating unit. The detection sensor may be a light detection sensor configured by a light emitting diode and a photodiode for outputting the detection signal corresponding to the received light quantity, but is not limited thereto. If the detection sensor is the light detection sensor, the signal level of the detection signal changes by the insertion of the external memory to the external memory accommodating unit, and thus the display control apparatus 1000 can perform the determination of step S100 based on the detection signal.

It should be recognized that the display control apparatus 1000 can perform the determination of step S100 not only when the external memory is accommodated in the external memory accommodating unit, but also when the user performs a predetermined operation.

The display control apparatus 1000 does not proceed the process unless determined that the external memory is detected in step S100.

If determined that the external memory is detected in step S100, the display control apparatus 1000 determines whether or not a database exists in the external memory (S102). The display control apparatus 1000 can perform the determination of step S102 depending on whether or not a file (or file group) of a predefined file name exists, but is not limited thereto.

<When Determined that Database does not Exist>

If determined that the database does not exist in the external memory in step S102, the display control apparatus 1000 sets the folder view mode (S110; setting of second display method). The display control apparatus 1000 displays the images recorded in the external memory based on the display mode set in step S110 (S108).

Although not shown in FIG. 5, the display control apparatus 1000 can store the display mode set when displaying the image in step S108 in a storage unit (hereinafter described) arranged in the display control apparatus 1000. An example where the display control apparatus 1000 stores the set display mode as “display mode holding data” in the storage unit will be described below.

Although not shown in FIG. 5, the display control apparatus 1000 can newly create a database if determined that the database does not exist in the external memory in step S102. The database created in such case corresponds to the database in the initial state in which the images recorded in the external memory is not registered.

As described above, if determined that the database does not exist in the external memory in step S102, the display control apparatus 1000 displays the image in the folder view mode (second display method) as shown in FIG. 1. Therefore, the display control apparatus 1000 can enhance the convenience and the operability of the user in displaying the image.

<When Determined that Database Exists>

If determined that the database exists in the external memory in step S102, the display control apparatus 1000 determines whether or not the database is usable (S104). Here, the display control apparatus 1000 can determine that the database is not usable based on the criterion indicated in (a) and (ii) below, but the criterion is not limited to the following.

(i) Determination Based on Bersion of Database (Determination Based on Compatibility)

The display control apparatus 1000 reads out from the external memory information (e.g., version number etc.) of the version set for the database recorded in the external memory. The display control apparatus 1000 then compares the version of the database indicated by the read information of the version and the version of the database to which the display control apparatus 1000 corresponds to determine whether or not the database is usable. For instance, the display control apparatus 1000 determines that the database is usable when the version of the database read out from the external memory is lower than or equal to the version of the database to which the display control apparatus 1000 corresponds. The display control apparatus 1000 determines that the database is not usable if the version of the database read out from the external memory is higher than the version of the database to which the display control apparatus 1000 corresponds.

As described above, the display control apparatus 1000 can display the images recorded in the external memory using the database to which it has compatibility by performing the determination based on the version of the database. As the display control apparatus 1000 performs the determination based on the version of the database, the display control apparatus 1000 can prevent various errors such as not being able to read out the information registered in the database or breaking the database to which it does not have compatibility.

(ii) Determination Based on Readout Result of the Database

The display control apparatus 1000 reads out the database from the external memory. The display control apparatus 1000 determines whether or not the database is usable based on whether or not the read out database is normally read out. Here, cases where the database recorded in the external memory is the file (or file group) in which only the file name is correct or where the database is altered at the binary level are given as an example in which the display control apparatus 1000 does not correctly read out the database.

As described above, the display control apparatus 1000 can prevent errors such as not being able to read out information registered in the database by performing the determination based on the readout result of the database.

If determined that the database is not usable in step S104, the display control apparatus 1000 sets the folder view mode (S110; setting of second display method). The display control apparatus 1000 then displays the images recorded in the external memory based on the display mode set in step S110 (S108).

As described above, if determined that the database is not usable in step S104, the display control apparatus 1000 displays the folder view mode (second display method) as shown in FIG. 1. Therefore, the display control apparatus 1000 can enhance the convenience and the operability of the user in displaying the image.

If determined that the database is usable in step S104, the display control apparatus 1000 sets the stored display mode (S106; setting of first display method). The display control apparatus 1000 can perform the process of step S106 based on the display mode holding data stored in the internal memory to be hereinafter described. The display mode indicated by the display mode holding data includes the folder view mode shown in FIG. 1, the date view mode shown in FIG. 3, and the favorite view mode shown in FIG. 4, but is not limited thereto.

The display control apparatus 1000 displays the images recorded in the external memory based on the display mode set in step S106 (S108).

As described above, if determined that the database is usable in step S104, the display control apparatus 1000 displays the image in the stored display mode (first display method). Therefore, the display control apparatus 1000 can enhance the convenience and the operability of the user in displaying the image.

Through the use of the processing method shown in FIG. 5, the display control apparatus 1000 can selectively set the first display method or the second display method based on the existence of the database or whether or not the database is usable, and display the images recorded in the external memory. Therefore, the display control apparatus 1000 can realize the processes (A) to (C) described above by using the processing method shown in FIG. 5, whereby the convenience and the operability of the user in displaying the image can be enhanced.

SECOND EXAMPLE

Through the use of the processing method shown in FIG. 5, the display control apparatus 1000 can realize the processes (A) to (C) described above. However, the processing method in the display control apparatus 1000 according to the embodiment of the present invention is not limited to the first example of the processing method shown in FIG. 5. A second example of the processing method in the display control apparatus 1000 will now be described. FIG. 6 is a flowchart showing the second example of the flow of process in the display control apparatus 1000 according to the embodiment of the present invention. Here, FIG. 6 shows an example of the process of when the display control apparatus 1000 displays the images recorded in the external memory, similar to the first example shown in FIG. 5.

Similar to step S100 shown in FIG. 5, the display control apparatus 1000 determines whether or not the external memory is detected (S200). The display control apparatus 1000 does not proceed the process unless determined that the external memory is detected in step S200.

If determined that the external memory is detected in step S200, the display control apparatus 1000 determines whether or not a database exists in the external memory (S202), similar to step S102 shown in FIG. 5.

<When Determined that Database does not Exist>

If determined that the database does not exist in the external memory in step S202, the display control apparatus 1000 newly creates the database (S212). The database created in step S212 corresponds to the database in the initial state in which the images recorded in the external memory is not registered.

When the database is created in step S212, the display control apparatus 1000 sets the folder view mode, similar to step S110 shown in FIG. 5 (S214; setting of second display method). The display control apparatus 1000 displays the images recorded in the external memory based on the display mode set in step S214 (S210).

Although not shown in FIG. 6, the display control apparatus 1000 can record the display mode set when displaying the image in step S210 in the display mode holding data.

As described above, if determined that the database does not exist in the external memory in step S202, the display control apparatus 1000 displays the image in the folder view mode (second display method) shown in FIG. 1, similar to the first example shown in FIG. 5. Therefore, the display control apparatus 1000 can enhance the convenience and the operability of the user in displaying the image.

In FIG. 6, a method in which the display control apparatus 1000 generates the database in step S212 has been shown, but it is not limited thereto. For instance, the display control apparatus 1000 may not create the database and may perform the process of step S214 if determined that the database does not exist in the external memory in step S202. It should be recognized that the display control apparatus 1000 can perform the process of step S214 even if the generation of the database fails in step S212.

<When Determined that Database Exists>

If determined that the database exists in the external memory in step S202, the display control apparatus 1000 determines whether or not the database is usable (S204), similar to step S104 of FIG. 5.

If determined that the database is not usable in step S204, the display control apparatus 1000 set the folder view mode (S214; setting of second display method). The display control apparatus 1000 displays the images recorded in the external memory based on the display mode set in step S214 (S210).

If determined that the database is not usable in step S204, the display control apparatus 1000 displays the image in the folder view mode (second display method) as shown in FIG. 1, similar to the first example shown in FIG. 5. Therefore, the display control apparatus 1000 can enhance the convenience and the operability of the user in displaying the image.

If determined that the database is usable in step S204, the display control apparatus 1000 determines whether or not “number of image registered in database>N (N is a natural number)” (S206). The value of N may be a predefined value (e.g., 0 (zero)), but is not limited thereto. For example, the display control apparatus 1000 can set the value of N to an arbitrary value according to the operation signal corresponding to the user operation transmitted from the operation unit (hereinafter described).

Therefore, the display control apparatus 1000 can prevent errors such as not being able to read out the information registered in the database as the information is not recorded by performing the determination based on the number of images registered in the database.

If determined as not “number of image registered in database>N” in step S206, the display control apparatus 1000 sets the folder view mode (S214; setting of second display method). The display control apparatus 1000 displays the images recorded in the external memory based on the display mode set in step S214 (S210).

If determined that the number of images registered in the database is not greater than a predetermined threshold value (N) in step S206, the display control apparatus 1000 displays the image in the folder view mode (second display method) as shown in FIG. 1. Therefore, the display control apparatus 1000 can enhance the convenience and the operability of the user in displaying the image.

If determined that “number of image registered in database>N” in step S206, the display control apparatus 1000 sets the stored display mode (S208; setting of first display method), similar to step S106 of FIG. 5. The display control apparatus 1000 displays the images recorded in the external memory based on the display mode set in step S208 (S210).

If determined that the number of images registered in the database is greater than a predetermined threshold value (N) in step S206, the display control apparatus 1000 displays the image in the stored display mode (first display method), similar to the first example shown in FIG. 5. Therefore, the display control apparatus 1000 can enhance the convenience and the operability of the user in displaying the image.

Through the use of the processing method shown in FIG. 6, the display control apparatus 1000 can selectively set the first display method or the second display method based on the number of images registered in the database and the like, and display the images recorded in the external memory. Therefore, the display control apparatus 1000 can realize the processes (A) to (C) described above by using the processing method shown in FIG. 6, similar to when using the processing method shown in FIG. 5, whereby the convenience and the operability of the user in displaying the image can be enhanced.

THIRD EXAMPLE

The processing method of when the display control apparatus 1000 displays the images recorded in the external memory has been shown as the first example and the second example of the processing method in the display control apparatus 1000. However, the display control apparatus 1000 according to the embodiment of the present invention is not limited to displaying the images recorded in the external memory, and may display the images recorded in the internal memory (recording medium). The internal memory is a unique recording medium (basically recording medium that is not used when removed) arranged in the display control apparatus 1000 such as the hard disk, and the user can generally freely access the internal memory. That is, the user can perform various operations on the internal memory such as creating a folder according to the DCF standard, recording data to the internal memory, deleting the recorded data, altering the recorded data, or formatting the internal memory. Thus, even if the display control apparatus 1000 stores the database in the internal memory at one time point, the display control apparatus 1000 may not be able to display the images using the database at another time point due to formatting of the internal memory, deletion or alteration of the database, and the like. A process of when displaying the images recorded in the internal memory will now be described as a third example of the processing method in the display control apparatus 1000.

FIG. 7 is a flowchart showing the third example of the flow of process in the display control apparatus 1000 according to the embodiment of the present invention. Here, FIG. 7 shows an example of the process of when the display control apparatus 1000 displays the images recorded in the internal memory (recording medium).

The display control apparatus 1000 determines whether or not to display the image (S300). The display control apparatus 1000 determines to display the image when the operation state changes from the imaging mode of performing imaging to the display mode of reproducing the image, but is not limited thereto. For example, the display control apparatus 1000 may determine to display the image based on a predetermined operation signal transmitted from the operation unit (hereinafter described) according to the user operation.

If determined not to display the image in step S300, the display control apparatus 1000 does not proceed the process.

If determined to display the image in step S300, the display control apparatus 1000 determines whether or not the database exists in the internal memory (S302). The display control apparatus 1000 can perform the determination of step S302 depending on whether or not a file (or file group) of a predefined file name exists in the internal memory, but is not limited thereto. For instance, the display control apparatus 1000 recognizes the existence of the database when a predetermined state is detected, holds the recognition result, and performs the determination of step S302 based on the held recognition result. The predetermined state includes a state in which connection between the display control apparatus 1000 and an external device such as PC (Personal Computer) (e.g., USB (Universal Serial Bus) connection and network connection) is cut (canceled), but is not limited thereto.

<When Determined that Database does not Exist>

The display control apparatus 1000 displays the images recorded in the internal memory based on the display mode set in step S310 (S308).

Although not shown in FIG. 7, the display control apparatus 1000 can newly create a database if determined that the database does not exist in the internal memory in step S302. The database created in such case corresponds to the database in the initial state in which the images recorded in the internal memory is not registered.

As described above, if determined that the database does not exist in the internal memory in step S302, the display control apparatus 1000 displays the image in the folder view mode (second display method) as shown in FIG. 1, similar to the first example shown in FIG. 5. Therefore, the display control apparatus 1000 can enhance the convenience and the operability of the user in displaying the image.

<When Determined that Database Exists>

If determined that the database exists in the internal memory in step S302, the display control apparatus 1000 determines whether or not the database is usable (S304). Here, the display control apparatus 1000 can determine whether or not the database recorded in the internal memory is usable similar to step S104 of FIG. 5.

If determined that the database is not usable in step S304, the display control apparatus 1000 sets the folder view mode (S310; setting of second display method). The display control apparatus 1000 displays the images recorded in the internal memory based on the display mode set in step S310 (S308).

If determined that the database is not usable in step S304, the display control apparatus 1000 displays the image in the folder view mode (second display method) as shown in FIG. 1, similar to the first example shown in FIG. 5. Therefore, the display control apparatus 1000 can enhance the convenience and the operability of the user in displaying the image.

The display control apparatus 1000 can display the image recorded in the internal memory based on the display mode set in step S306 (S308).

As described, above, if determined that the database is usable in step S304, the display control apparatus 1000 displays the image in the stored display mode (first display method), similar to the first example shown in FIG. 5. Therefore, the display control apparatus 1000 can enhance the convenience and the operability of the user in displaying the image.

Through the use of the processing method shown in FIG. 7, the display control apparatus 1000 can selectively set the first display method or the second display method based on the existence of the database or whether or not the database is usable, and display the images recorded in the internal memory. Therefore, the display control apparatus 1000 can realize the processes (A) to (C) described above by using the processing method shown in FIG. 7, whereby the convenience and the operability of the user in displaying the image can be enhanced.

If determined to display the image in step S400, the display control apparatus 1000 determines whether or not the database exists in the internal memory (S402), similar to step S302 shown in FIG. 7.

<When Determined that Database does not Exist>

If determined that the database does not exist in the internal memory in step S402, the display control apparatus 1000 newly creates the database (S412). The database created in step S412 corresponds to the database in the initial state in which the images recorded in the internal memory is not registered.

When the database is created in step S412, the display control apparatus 1000 sets the folder view mode, similar to step S110 shown in FIG. 5 (S414; setting of second display method).
